Covid 7/16: Becoming the Mask

Previous week: Covid 7/9: Lies, Damn Lies and Death Rates

Two weeks ago I predicted a surge in Covid deaths starting on July 2 and picking up on July 7.

On July 6, the rolling 7-day average of Covid deaths reached a local low of 480.

Seven days later that average was 721, almost exactly 50% higher. It’s since pulled back slightly to 696.

No doubt holiday delays are a small portion of that story, and helps to explain why things didn’t pick up until after the holiday backlog was gone, which I failed to anticipate at the time. That is a small part of this story, but only a small part.

The good news is that, once again, things are getting worse slower than I would have anticipated two weeks ago. We might be remarkably close to turning the corner.

The other good news is that masks, especially cloth masks, might be a lot of the story of reduced death rates, by reducing initial viral loads. Despite have a full debate and writing a whole post about this, I still didn’t take this possibility seriously enough in the last few explorations. That wouldn’t be quite as good news as the virus becoming less deadly, but it’s probably the second best possible news.

Where do we go from here? When and where will deaths and infections peak? How long until we turn things around? How much locking down do we have left in the tank after all?

Let’s run the numbers.

It’s clear that things were worse this week than last week. There were more positive tests in all four regions. The West may have managed to reimpose enough controls slash adjust enough behaviors to be in a better spot, in particular with California and Arizona looking like they may have turned the corner. The Midwest and South don’t share that pattern. The Northeast has reason to worry, and Pennsylvania is attempting today to walk back some of its reopening.

But it’s also clear that the second derivative improved, and the trend line broke. Positive test rates are only slightly up, and didn’t seem to rise much day to day throughout the week. It’s possible that the second wave peak of infections will be in July. There was a large jump in test count this week, and wasn’t one last week, so the smooth lines on the infection count graphs are misleading. There’s good reasons to mostly be optimistic here.

New York has had a scary last two days, but mostly I see this as the state having its internal problems under control while importing cases from elsewhere on a continuous basis. One friend had a neighbor infected because they flew to Florida for a July 4 party, which qualifies for first rank Covidiot status.

New York and New Jersey continue to see declining death counts week over week, despite infection rates that clearly stabilized three or more weeks ago. Given how rapidly this is continuing, this is a sign that deaths substantially lag more than a mere few weeks. I can accept declining real death rates, but not this fast. As usual, see my spreadsheet for full details.

Mysterious Deaths Solved

Twice previously I’d talked about the apparent rise in ‘mysterious deaths,’ or those classified under R00-R99. The speculation I’d read was that this was being used to hide increasing numbers of Covid-19 deaths, which seemed plausible to me. Last week, I finally got linked to raw data, and posted an analysis.

I learned a few things along the way (see post for details), but the big thing is that no, this wasn’t a massive conspiracy or distributed cover-up or anything like that. It is our system for classifying deaths being slower than molasses, often taking months to figure out causes of death. So most of the increase in mysterious death in recent weeks will fade away over time, leaving a bump not big enough to impact the grand scheme of things.

Mysterious Tests Incoming

However, in the data becoming fraudulent front, we now have a new problem on its way.

According to reports I have seen, the Trump administration has awarded a no-bid contract to a private corporation, and instructed hospitals to send their test results for compilation to this company, rather than sending them to the C.D.C. 

I’ve been hard on the C.D.C. lately. I think it’s been deservedly so. I disagree with their policy recommendations, and what I presume is the motivation behind them making those recommendations. I’m also still rather frustrated with the botched initial testing kits and how that was handled.

This, however, is something else. As far as I can tell, Trump was displeased that the C.D.C. refused to neuter its school reopening guidelines when he requested they do so, and continues to engage in the heinous act of telling people how often Americans test positive for Covid-19. Frustrated for long enough, he has decided to do something about these scandals, and strike back.

I hope this is a false alarm, and either the reports are incorrect, or hospitals will ignore this new instruction and send the data to the C.D.C. (and/or make it public) regardless of whether they also send the data to the new provider. Alas, it seems the reports are probably true.

We must remain vigilant. Ensure the worst does not occur, if we can do that. Recognize the worst if it does occur. It’s less bad to slow the statistical compilation of test results than to actually slow the testing down, as Trump previously explicitly confessed to doing. It’s still very, very bad.

It’s an interesting question whether it’s better or worse to falsify the records outright, which likely is his preference here, than to actively slow down testing. My gut and aesthetics say falsifying the records would actually be worse, as hard as that might be to defend to many.

From here on in, we need to constantly ask the question, are the numbers real, or are they manipulated lies, and if so to what extent.

The good news is that the Covid Tracking Project does not anticipate that this will interfere with their methodology, since it is assembled at the state level. It would be better if the Federal Government compiled accurate data, for many reasons, but as long as we have the state-level data that was all , hopefully we should be fine.

Where Is The Line

This week, Robin Hanson noted that many media outlets and experts predicted a surge in Covid-19 deaths Real Soon Now, and asked if any of them were offering betting odds. In particular, he asked about odds on when we would reach an average of 1100 daily deaths, roughly midway on a log scale between deaths at the time and deaths at the previous peak.

Needless to say, no. No one was offering betting odds. With notably rare exceptions, such people never offer even probabilities, let alone probability distributions, let alone betting odds of any kind, let alone betting odds on people dying. We are lucky we get (actively and openly distorted to account for how regular people interpret and react to probabilities) odds on tomorrow’s weather. On its face it is a rather silly question.

As a request for such odds, from those such as myself who might ever offer them, rather than attempting to be a rhetorical argument against such ‘experts,’ it is far more reasonable.

Thus there were three questions.

What is my fair price?

What is the price at which I am confident I have substantially the best of it?

Is this a topic on which one can or should bet, given it is people dying?

To figure out how I expected short-term death counts to go, I looked at a few inputs.

The number of infections was going up rapidly, but how much? Positive test rates had bottomed out nationwide around 4.4%. At the time of the question, it looked like our new rate was roughly double that off 50% more tests. So it seemed like the default was that infections had somewhat more than doubled. It also seemed clear that death rates had stopped declining by 7/2, if you corrected for the holiday weekend, with the previous lowest true rate being at or around around 6/9. So we were looking at just over a three week delay there, with about enough increased cases to get us to around 1100.

There’s the argument that death rates were declining. That does seem to be the case, but how rapidly is that going to keep happening? Are conditions further changing? If anything, I’d expect death rates to rise again, because hospitals are becoming overwhelmed, and that should be the primary change from now to next month in terms of outcomes.

Thus, if we assume that reported infections hit the necessary levels around 7/9, something around 8/1 is when I would expect to see us back at 1100 deaths per day under baseline scenarios. It is already too late to impact this result much. That’s about why I replied that my fair was 8/1. To get a betting line, I asked how long it would take to take care of any plausible delay, and to account for things clearly looking sufficiently bad, and came up with 8/15. I offered a small wager at that point, and got no reply or counter-offer.

It is now close to a week later. I’d move up my timelines slightly, but only slightly, as the rises that we’ve seen were not unanticipated.

All that of course assumes the data is not likely to become (substantially more) fraudulent and hide deaths. Given the section above, I’m not sure we can assume that.

Predicting The End

If one were to extend prediction farther into the future, what is the best guess for what will happen over the next few months?

Here’s how I currently roughly think about projecting things into the future.

There are lots of variables, but we know a lot about what values they likely take. If I was going to go for a baseline scenario, I have clear best guess assumptions for them.

One big unknown is the policy response. This means both whether governments at various levels will be willing and able to impose restrictions, and to what extent citizens will choose to abide by those restrictions and/or do voluntary other action to slow the spread.

In my baseline scenario, we don’t see much difference in action from what we are seeing now, and thus the background rate of infection does not change much on this basis. I do expect to get modestly increased mask adherence over time, but I don’t want to count on too much gain from that.

Are there events coming up that will make the situation worse, and could create a third wave or sustain the current one? Yes. There’s one hell of an event coming up in September called school. It won’t come full blast, but it will happen to a large extent in many places, including many places it shouldn’t happen.

This also plays into my model that there are control systems at work. When things get worse or better, people adapt their behaviors.

The other question is how rapidly herd immunity sets in as a function of confirmed infections. That means we need to convert from confirmed infections to actual infections, decide how long we believe immunity lasts, and then guess how impactful those people being immune is on the new rate of infection.

As I have stated many times before, I will state again that I see no evidence that immunity is going to run out any time soon for substantial numbers of previously infected individuals. Thus, I’m going to assume that immune in context means immune period, for as long as is relevant here.

My best conservative guess for the current multiplier from identified to true cases is at least 5 times the number of confirmed infections, and it could still be as high as 10. It’s clear death rates have dropped. Previously a rate of 1% was my conservative estimate, there’s a large delay on deaths coming in, and the current overall CFR without NY/NJ is sitting just above 3%, albeit with a large number of cases that haven’t seen their final outcomes yet.

What does a given amount of immunity mean for the rate of infection? As I’ve long said, much more than one would naively expect. Power laws apply. My best guess is that the first 5% that we’ve already seen actually represents at least a 20% reduction in infection rates, and that a 10% immunity rate would be good for at least 30%. Again, I consider these very conservative guesses. It could be a lot more than that, especially if there is existing immunity slash variation in vulnerability, and also especially if many people continue taking extreme precautions while others are forced to or choose to accept massive exposure. Demographics shows that risks for different populations varies greatly, so there’s no good way to deny this effect.

Real rates of infection have roughly doubled over the last month. That’s about six serial intervals, meaning a best guess for general R0 (while noting that there is a ton of regional variation) of about 1.12. Thus, we could expect that a 10% reduction would get us back to roughly 1.0. If we have to do it all with immunity, going from roughly 5% to roughly 10% should definitely do it, barring compensating adjustments in behavior. If behaviors adapt to intentionally put immune people in positions of risk, things could improve further.

How long will all that take? Right now a reasonable guess is we have at least 300,000 true cases per day, so that would take at most three months if the case rate was already stable. It’s not stable under this scenario, so this should be closer to two. We then have to deal with schools reopening, and with changes in the weather, and with changes in which populations are currently infected, and so forth.

No matter how bad things are now, within the range of possibilities, we should be turning the corner, with the underlying infection counts starting to drop, by mid September, and definitely by the end of September. If things are worse now, then we’ll get more immunity faster, which will make up for it. That doesn’t mean things are even as good then as they are now, merely that they start improving.

Deaths likely peak somewhere between 1,200 and 2,500 per day. Less deaths than that would mean death rates have fallen a lot more than I expect, or herd immunity works the way my intuitive models think it does and therefore is already setting in to a large extent, either because power laws are more powerful or more people are immune than the conservative assumptions. I do think there’s a bunch of probability mass in ‘death rates have dropped and herd immunity is already turning the tide so we peak relatively soon at a number that isn’t that high.’ Note that this is compatible with usually hitting 1,100 deaths relatively soon, because in relatively good scenarios the peak comes relatively soon.

More deaths than about 2,500 would mean a health care system collapse.

Then we see if schools set things up for wave three. Given experiences in various places including Israel, as well as common sense and my belief in physics, I believe that schools will increase infection rates substantially wherever they are open, and doing ‘part time’ is going to not help much – see the discussion last week, since my analysis has not importantly changed.

There wouldn’t be a fourth wave unless slash until immunity fades, by which time I hope slash expect a vaccine. Vaccine progress tentatively looks quite good.

Remembering to Take Initial Viral Load Seriously

Suddenly this week it is out there in the zeitgeist that masks could reduce your own risk from Covid-19, not only by reducing your risk of infection somewhat, but also by reducing your initial viral load. Thus, if you are wearing a mask and get infected, your illness can be expected to be less severe.

Masks reducing initial viral load is obviously correct because physics. The question is only whether that load matters. Because our society is, in effect if not in principle, fundamentally opposed to science and learning things, we don’t know. Priors say that it is likely true.

Why was this message ignored for so long? Why is it still not being broadcast aggressively? This seems like a much more convincing argument to get people to mask up. Protecting others is great, but protecting the wearer will always be a contribution to one’s favorite charity. And the idea of ‘get less sick if you get sick’ is if anything more appealing than not getting sick as often for those not at much risk, because you get immunity on the cheap, as it were. For those at risk, the benefit is clear.

Shout it from the rooftops, I say. Any reasonable prior says we should expect it to be true. People should wear masks because it protects everyone involved by reducing the severity of any infections that do happen, in addition to preventing many infections from happening at all. Great pitch.

From what I can tell, the surge in discussion of this comes from this LA Times article. Someone wrote a snappy headline and framed this as ‘mounting evidence’ to fit it into the narrative. Kodus to the authors for doing so, as this seems to be an honest write-up. Highly above average journalism.

It also might come somewhat from this paper.

The evidence in it that could possibly have been news was the asymptomatic rate being high among some groups that were given masks. I worry these have a lot to do with the details of the clusters in the question other than masks, and also hope that the asymptomatic rate is actually very high in general, and also we shouldn’t need this information. But if it’s what gets people’s attention, great, let’s go with that.

The article also points to death rates in mask-wearing countries as highly suggestive, which could have been pointed out any number of times previously.

Why haven’t I been mentioning this recently, until now? Why didn’t this even make the list of hypotheses when discussing lowered death rates? What does this suggest about why everyone else doesn’t talk about it?

I pretty much have no excuse, given I did a bunch of work on the subject.

I have even less excuse given I take active measures to minimize my exposure in this way all the time. It’s central to how I’ve structured my choices of actions, worrying less about small stuff while keeping the small stuff small, and taking extreme measures to avoid big risks.

Despite all that, it faded from my mind in the context of writing, and I stopped thinking about it in that context until I was reminded. I need to think more about the details of how I allowed that to happen, so similar things don’t get forgotten in the future.

In the meantime, yes, this. Wear a mask to protect yourself and others, not only from catching Covid-19, but to ensure relatively mild cases for those who do catch Covid-19.

Sports Go Sports

It’s time.

Athletics are number one. Participants are heroes. Go team, yeah!

Except all completely straight. It makes it that much better to defeat you.

In case that wasn’t clear: We’re great, and also, you suck.

In an world of increasingly toxic and escalating wars between ingroup and outgroup, a never-ending parade of mutual cancellations and Aysmmetric Justice. In world of increasingly unfair play. In a world of increasingly falsified records. In a world where we’re afraid to go outside and entertainment production has come to a screeching halt.

We need sports. Real American sports. To teach us what it means to be the loyal opposition engaged in fair play. To raise up high those who accomplish great things, rather than looking for what we can tear down. To remind us to keep good statistics so as to understand the world. To have something to watch and then argue about all day without destroying Western civilization – the destruction of which, in an increasingly hot take, I think would be a bad thing.

Sports. Now, more than ever.

For those of you who don’t get the sports aesthetic, that’s the best I can do without writing a difficult post that’s been on my stack for a long time. Eventually, I swear.

Things are rather desperate. I tried watching NASCAR. If it hadn’t been for the ‘competition caution’ I would have kept watching.

I have missed being temporarily adjacently victorious, or at least temporarily adjacently agonizingly defeated, so much.

It’s time.

Baseball needs to happen on schedule next week, or I am going to be a very sad and angry panda. Looks like they’re going to at least try. Basketball is needed, too.

And remember: No football, no peace.

Make no mistake. There are going to be problems. Athletes are going to test positive, not only on arrival but during the season. The show must go on.

My instinctual first response is, take one for the team. Where that team is not only your team, but also America.

Sports as a whole bring joy to hundreds of millions of Americans. Individual events frequently bring joy to millions. They bring us together.

If a few athletes get sick as a result, that’s bad, and let’s do everything we can to prevent it that’s compatible with playing, but, well, is any of this meaningfully new?

How many weeks of playing football is worse for your long term health than definitely getting Covid-19? When a huge portion of young healthy people are getting it anyway? When a lot of athletes are getting it off of the field before play even starts? 

By participating in sports, such players get access to constant testing. They get far superior isolation procedures, in place of what would otherwise be frequent high-risk behavior for many of them.

It isn’t obvious to me that playing even raises the risk of infection for them at all. Let alone net increases the resulting health risks. It seems like it’s mainly Copenhagen Interpretation of Ethics, where these infections are things we’re interacting with and thus responsible for, even if there aren’t net more of them, whereas other infections we are not responsible for.

As for those who ask if it’s ‘responsible’ to ‘use all this testing capacity’ I remind everyone involved that there isn’t a constant amount of capacity over this kind of time frame. The leagues will pay good money for it so we’ll make more. The scandal is that the government is not doing that same thing. Back in March, I thought this argument was mostly nonsense but it made some sense. Now in July, it’s completely vacant.

We will do our best, and deal with problems when they arrive, but fundamentally, The Show Must Go On. If we occasionally need to hit pause to do a re-quarantine, well, so be it. But again. The. Show. Must. Go. On.

A seemingly troubling sign is that colleges are pushing sports into the spring, or limiting games only to conference play. I call upon us to embrace the upside of these actions.

By focusing on conference play, we make every game good. What was the point of cupcake games to begin with? There are 12 or more teams in each conference, so we can get a full schedule of good games. Every game counts. Every game matters. We should still do our best to do a rivalry week at the end, when there’s no risk of cross-contamination afterwards, to allow the most important out of conference game for each team. But that’s good enough. This is a better schedule. 

The college football playoff should by all rights expand, of course, because without cross-conference play it’s impossible to compare properly and choose who gets left out. Another opportunity! Let’s expand to six teams for this year. With round robins or close to it, each conference can send their champion, and the committee can choose one team at large to join them. Play two games prior to the bowls to get down to four, then play the Rose Bowl Pac-12 vs. Big 10, and Sugar Bowl as SEC vs. ACC/Big-12, as tradition mandates, or replace losing champions from the first round with whoever beat them. Championship game in the Orange Bowl a week later.

Even better, let’s intentionally postpone all of this until the Spring. 

Every year, sports fans face a cycle. Baseball provides the boys of summer. Then we have two forms of football plus the MLB playoffs, so the days are packed. There’s games all Saturday, all Sunday, Monday night, Thursday night and usually other nights too, and that’s without the basketball or baseball. One can’t keep up! Then we have NBA plus both footballs, and they’re mostly packed again. Then February rolls around and I hope you like shooting hoops, cause that’s all you’re going to be doing until April.

Or, alternatively, we could finally do the right thing. NFL plays Saturday and Sunday plus Monday night, gets rid of that dreadful Thursday night game. This allows full testing periods between games, so any flare-up gets caught. It gives us the chance to watch lots more NFL, and fight less with baseball and the World Series.

Then, once the NFL is down to four teams, we start playing NCAA Football in January. Conference play plus a final rivalry week for non-conference opponents. Like NFL, they get to play on both Saturday and Sunday, so now we get full Football weekends all the way through April. Then we play the bowl games in the north rather than the south.

Come on, everyone.

Let’s do it and be legends.

Dreams of a Vaccine

This week we get to end on legitimately great news. The vaccines look like they work!

Check out this Nature paper. All 36 patients responded. Excellent. Both Moderna and Oxford look like they’ve got strong candidate vaccines and are making rapid progress.

Meanwhile, China is confident enough in its candidate to use it for its military. That’s not something one does without high confidence in safety and a strong prior that it’s likely to work.

There’s also this call for challenge trials, from some people whose voices have some chance of being heard. Still a long shot, but Americans are known for doing the right thing after exhausting all alternatives. It might be time!

I Have Decided To Give Back to the Community

However, unlike Twitter, I have not been hacked, so I will do this via providing hopefully useful information, rather than having it take the form of providing a Bitcoin address. I thought about it, sure, cause who knows what might happen. But it seemed rather tacky.

See everyone next week.

    “From here on in, we need to constantly ask the question, are the numbers real, or are they manipulated lies, and if so to what extent.”

    I’ve got a bad case of Tinfoilitis, so that’s been my mindset since the start. There are people in the DoD that have accurate numbers for deployed units because they’ve been running an independent testing program and they have a huge vested interest in (internally) knowing the real rate. From the little I do know, my main takeaway is “Don’t Panic” and combined with my Darwinian priors about how viruses evolve, my guess is that the lethality attenuation is at least somewhat real.

    But yeah- the official numbers should be looked at with extreme skepticism. The issue was politicized from the start, and many people see this election year as a particularly important one so there’s probably been shenanigans from all quarters.

    Regarding the Robin Hanson bet – what is your opinion on covid19-projections? Their historical performance has been quite good and they’ve correctly predicted a surge after July 4th: https://covid19-projections.com/about/#historical-performance.

    • TheZvi says:

      Seems like they’re making some obvious mistakes? But it’s hard to always make predictions.

    • TheZvi says:

      Better answer now that I have more time. IHME was so bad I had a post ripping it to shreds. This could be better. But if you look at the graphs where they evaluate themselves, they’re looking at cumulative counts rather than marginal counts, with most deaths already in the past, so it’s easy to “look” good on those graphs by projecting anything reasonable, and there’s been no big changes in the period. So it’s hard to know, and their presentation is a mess. What’s their value add?

  3. sandorzoo says:

    Any thoughts on weather impacts going into the fall? Where I grew up, first frost was usually around the end of September.

    • TheZvi says:

      After what happened with summer weather, it’s hard to say. Presumably it will be good for the South and bad for the Northeast/Midwest, because it will drive southerns indoors, and the north indoors? But we really don’t know, and likely never will due to confounding.

  4. sandorzoo says:

    Recent survey data finds that a strong majority of the public see challenge trials as ethical:

  5. Brett Bellmore says:

    I’m somewhat interested in the reports that immunity to this virus may be mediated by T cells as much as antibodies. And that people can have T cell mediated immunity to Covid 19 without ever having been exposed to it or SARS, due to the T cells targeting proteins Covid has in common with some cold viruses.

    Click to access S0092-8674(20)30610-3.pdf

    ” Importantly, we detected SARS-CoV-2-reactive CD4 + T cells in 40%–60% of unexposed individuals, suggesting cross-reactive T cell recognition between circulating ‘‘common cold’’ coronaviruses and SARS-CoV-2.”

    This suggests that any modeling of build up of immunity to Covid 19 has to take into account a substantial population who were already (somewhat!) immune without having to be infected, but don’t show up on tests for circulating antibodies. Really great news if true.

    Since they found this relationship between four “common cold” viruses and Covid 19, and the common cold is relatively benign, I wonder if they could be used as a somewhat protective live vaccine?

    • TheZvi says:

      A functioning civilization would know the answers to these questions. We do not know those answers. I find this interesting too, and find it highly plausible that a substantial number of people start immune – if it’s from infections, then there will be places where that isn’t true, so there being super-spreader events with high penetration isn’t evidence against it. But we also don’t have a ton of evidence for it, either. Dunno how we’ll know, in practice, given our unwillingness to do the work.

      • Brett Bellmore says:

        I suppose I share your complaint about a functioning civilization.

        I’ve compared the way epidemiologists operate, to only turning on the seismographs when buildings start shaking, or hauling out the wind gauge when you see a tornado. In my experience doctors show a remarkable lack of curiosity about what you might be infected with, until you’re at the verge of dying. It’s been decades since I saw one take a swab to culture.

        Medicine needs to be more like weather forecasting, continually taking detailed measurements to avoid being taken by surprise. It should be routine to have any infection bad enough to take you to a doctor be sequenced, for instance. The cost of sequencing genes has dropped enough for this to be feasible, at least on a random sample basis, and with effort it could be made affordable in every case. Doing this would have really paid off with Covid 19, we’d have known we had a potential pandemic on our hands likely some time late last year.

        The problem here is that all institutions decay, have their resources diverted to non mission critical activities, unless frequently challenged by existential threats. Rather similar to the way genetic traits decay if not maintained by evolutionary pressure. It’s been a long while since we faced something like this.

    There appears to be an outstanding disagreement between NFL owners and players over whether COVID will be classified as a “non-football injury,” which would allow the owners to withhold salaries if a player gets infected and cannot practice or play. IMO this seems like indefensible nickel-and-diming from the owners.

      I find it interesting that everyone always assumes the owners are the ones in bad faith. Who is nickel and diming who? This goes back to the question, if a football player gets Covid, is that *because of them playing football* or would they, or a similar number of players have gotten it anyway? With daily testing, are they actually at higher risk?

      Suppose that, as is realistic, between September 1 and January 1, 10% of all Americans get Covid-19, and 10% of NFL players also get Covid-19. Should they be paid? Why or why not?

      Typically, diseases are non-football, even if caught from other players, and NFL players presumably don’t catch diseases much more than other people, in general. This seems like the players wanting a change in policy and the owners pushing back, when the owners will likely need to play without fans and haven’t asked for any pay cuts otherwise.

      • Anonymous Bosch says:

        I don’t think the owners are operating in “bad faith” and that’s not really a synonym for nickel-and-diming. The owners are wealthy and able to weather a lack of gate receipts from other sources of income (>50% of revenue is TV money, on top of merchandising and licensing deals) and that loss will itself be mitigated by the lack of payrolls for stadium staff (who should in turn receive a robust basic income, but that’s another discussion). The average NFL player lacks these side gigs (endorsements are thin outside star QBs and all-pro defenders) and their “salaries” are mostly non-guaranteed.

        I’m being explicitly egalitarian here. If a group of people, whether it’s first responders or essential workers or NFL players, are expected to assume extra risk (which NFL practices and games are) for some abstract greater good or return to normality, that cost should not be borne by them alone, but supported in proportion from the people who will profit from said abstract greater good or return to normality.

        I don’t take a dim view of employees demanding policy changes in exchange for going back to work during a pandemic. That diseases are “typically” non-football carries little force in what will be a very atypical season. Many businesses with hourly employees that did not previously have paid sick leave policies have recently instituted them, due to the obvious incentive problems. The NFL should follow suit.

      • TheZvi says:

        Ah, ok. You’re right, the bad faith thing is my bad, it’s from all the MLB/MLBPA discussions.

        I agree that the NFL would likely to be wise to pay, as it’s a lot of goodwill for not that much money.

    You might be interested in following the NWSL? They’re quite active right now, according to people I know who partake in sports.

    • TheZvi says:

      Thanks for the suggestion. Alas, soccer doesn’t do it for me. If it did we have Bundesliga and EPL and so forth, but despite doing things like “make world’s best accurate soccer live automated dealer” and watching a ton of games, when the money’s gone, I just can’t get into it at all. Whereas with football and baseball, I miss the gambling some, but everything definitely works.

    The more I think about it, the more I realize… How useful are tests in a country where contact tracing cannot be done efficiently? So far it seems that tracing in America failed to take off the ground anywhere except small isolated communities. So even if we magically started running 10x the current tests tomorrow (dropping the TPR below 1%), would it really improve America’s handling of the pandemic? Or vice versa – if NYC reduces their test capacity 10x, would it really worsen their pandemic? I do see the value in knowing where the hot spots are, but these could be easily detected via randomised testing too – no need for hundreds of thousands of daily tests.

    In other words – are we correct in placing high importance on TPR?

    • TheZvi says:

      I focus on TPR more because it tells me what’s going on rather than anything else. But yes, I think identifying cases is still super important. “Contact tracing” is great, but even knowing when you’re sick so you can isolate for real is even more important than the pre-emptive contact tracing, and there will be a lot of de facto tracing done privately because people tell others they were positive, etc.

    One issue with moving football to the spring is what you do in the fall of 2021. A spring football season would end in April or May, and asking players to start another full season in September is bound to lead to a ton of injuries.

    • TheZvi says:

      My suggestion is a permanent move, it’s just better! The transition year back might be a bit tricky, but with a year’s turnover being ~50% of starters or something, and most players not actually injured, I think it would be all right.

    Derek Lowe on T cell responses. This intersects with your discussion in interesting (though not yet easily testable) ways. Also you should be reading him if you’re not already. https://blogs.sciencemag.org/pipeline/archives/2020/07/15/new-data-on-t-cells-and-the-coronavirus
